Text size for 128x64 OLED Display

Looking some easy way to use large font size instead of standard.

Unless the display controller has different font sizes you will probably need to define your own font matrix character set and then address the display graphically.

Hello, i have this display.
I want to read this number 23.2 in all the screen space ...
Can i use big font to expand text size??

Thanks
